MCP server in Claude Desktop

Add AI Act Radar as an MCP server so Claude can query regulatory updates as a tool.

1. Open the config file

Edit ~/Library/Application Support/Claude/claude_desktop_config.json on macOS, or %APPDATA%\Claude\claude_desktop_config.json on Windows.

2. Add the server

{
  "mcpServers": {
    "ai-act-radar": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-fetch", "https://mcp.aiactradar.com/mcp/v1"],
      "env": {
        "AUTHORIZATION": "Bearer aiactr_REPLACE_WITH_YOUR_KEY"
      }
    }
  }
}

Claude Desktop currently calls MCP servers via stdio, so we wrap our hosted endpoint with @modelcontextprotocol/server-fetch as a proxy. (When Claude Desktop ships native HTTP MCP, replace the wrapper with the same URL/header config used in Cursor.)

3. Restart Claude Desktop

Quit and reopen. Claude logs MCP connections — check ~/Library/Logs/Claude/mcp.log if no tools appear.

4. Try it

Use ai-act-radar to summarise EU AI Act updates from the last
14 days that affect high-risk AI systems.

What Claude can ask the server

• query_ai_act_updates({ since, source_id, topics, severity_min, limit })
• get_obligation_for_role({ role, risk_category })
• summarize_changes_since({ since, topics, language })
• lookup_article({ article })
